The Circle by Sara B Strandberg and Mats Elfgren:
One night, when a strange red moon fills the sky, six school girls find themselves in an abandoned theme park, drawn there by a mysterious force. A student has just been found dead. Everyone suspects suicide. Everyone – except them.In that derelict fairground an ancient prophecy is revealed. They are The Chosen Ones, a group of witches, bound together by a power, one which could destroy them all. But they soon learn that despite their differences they need each other in order to master the forces that have been awakened within them. High school is now a matter of life and death. Because the killing has only just begun.
THE ANDALUCIAN FRIEND is the first book in a trilogy following Sophie, an ordinary Swedish woman, a nurse and single mother, who gets dragged into an incendiary conflict between two powerful crime syndicates and a group of corrupt police officers. ( Blurb from press release, which was found via Eurocrime)
Two cars collide head to head on a country road with little traffic. The collision is violent. Ten year old Cecilia is catapulted through the windscreen and killed. Five years later, criminal detective Walter Grohn gets a perplexing case on his desk – one dead taxi driver and his killer who has no idea why he committed the crime. The first murder is followed by others, all equally as brutal and inexplicable. Together with his talented assistant, Jonna de Brugge, he untangles threads that lead back to the very core of the Swedish justice/judicial system
